The %. implementation may change from time to time, but I don't think it
did in this case.
The implementation of ^. did, and might account for the difference. You
could check.

Hi all,
I perform the calculation
2 4 6 %. 1 2 3 ^/ i.2
for the test suite of my j package
https://github.com/vmchale/j-hs/blob/main/test/Spec.hs#L76
With J 9.01 this gave (5.995204332975845e-15, 1.9999999999999971) as a
result. With J902, it gives (7.105427357601002e-15, 1.9999999999999967).
Since the exact answer is (0, 2), this is ever-so-slightly more
incorrect! Any insights into why?
(I'm on x86_64 and Linux FWIW)
